Description

Information transmission method, information transmission device and communication device

The present invention claims priority of a Chinese patent application filed with the Chinese Intellectual Property Office on July 23, 2020, application number 202010718812.5, titled "Information transmission method, information transmission device and communication device", and in this application I am citing all of them.

The ^5th Generation (5G) New Radio (NR) system supports carrier aggregation (CA) and uses a plurality of component carriers for user equipment (UE) , CC) or cell configuration and activation, and also support cross-carrier scheduling under CA. In addition, NR also supports multiple transmission and reception panel (M-TRP) scenarios, and the UE can perform data scheduling and transmission/reception by means of a plurality of TRPs. In the current NR system, one cell only needs to be scheduled by one cell (i.e., either itself is scheduled or scheduled by another cell), and the primary cell is only the Primary Cell (PCell) It can only be scheduled by itself.

In order to enhance the control channel coverage, PCells are generally placed on low-frequency carriers. On the other hand, the bandwidth of the low frequency band is insufficient, and has already been deployed in other systems (eg LTE systems) in large numbers. Therefore, by configuring the high-frequency band carrier with the SCell and scheduling the PCell through the SCell, the problem of the limited capacity of the PCell control channel can be solved and the physical downlink control channel (PDCCH) overhead on the PCell can be reduced. there is.

Currently, NR maintains one blind detection budget for each scheduled cell. In the case of CA limited, the corresponding blind detection budget may be related to the subcarrier spacing (SCS) of the scheduling cell and the number of cells scheduled by the corresponding scheduling cell. If the SCell scheduling the PCell or the secondary cell group where it is located is dormant indicated by the downlink control indicator (DCI) of the PCell or SCell, in this case, if the Pcell and/or SCell Alternatively, if the blind detection budget or mapping is still performed according to the conventional method without considering the configuration of the Scell, some blind detection numbers cannot be used, which affects the PDCCH capacity and scheduling efficiency.

An embodiment of the present application is to provide an information transmission method, an information transmission device, and a communication device that solve the problem that some blind numbers cannot be used by performing blind detection budget or mapping without considering the configuration situation of Pcell and/or Scell.

Also, it is not specifically limited in this embodiment. As shown in Fig. 2, the method includes the following steps.

S210: Determine a target blind detection budget and/or a target mapping manner of the UE according to the scheduling configuration of the first cell and/or the second cell of the UE.

In an embodiment of the present application, the second cell supports scheduling by the first cell, or the second cell supports self-scheduling and the second cell is scheduled by the first cell. support that For example, the first cell may be a Scell and the second cell may be a Pcell.

In an embodiment of the present application, the target blind detection budget includes: a blind detection budget in the first cell; a blind detection budget in the second cell; and at least one of joint blind detection budgets in the first cell and the second cell. Whether the target blind detection budget specifically includes the blind detection budget of the first cell and/or the second cell may be determined according to the scheduling configuration of the first cell and/or the second cell.

In an embodiment of the present application, the target mapping method is a mapping method in which control units of the first cell and/or second cell are mapped to physical control resources. Here, the physical control resources include physical control resources of the first cell and/or the second cell.

In an embodiment of the present application, the scheduling configuration may be scheduling configuration information configured according to whether the first cell and/or the second cell satisfy a predetermined condition, for example, the first cell and/or the second cell. 2 Scheduling configuration information configured according to whether the cell is in a dormant state and/or in an inactive state.

In one possible implementation, the scheduling configurations of the first cell and the second cell include any one of a first scheduling configuration, a second scheduling configuration, and a third scheduling configuration.

In the above possible implementation manner, the first scheduling configuration is such that the first cell can schedule the second cell and the second cell cannot schedule itself, or the first cell schedules the second cell. capable of scheduling and the second cell does not schedule any cell; In other words, in the first scheduling configuration, the second cell can only be scheduled by the first cell, and the second cell cannot schedule at least itself. For example, when the second cell is instructed to be dormant or deactivated, the dormancy of the second cell may be specifically indicated through downlink control information (DCI) and deactivation may be indicated. or may also instruct dormancy and inactivation of the second cell through a Media Access Control (MAC) Control Unit (CE), or may also instruct Radio Resource Control (Radio Resource Control, RRC) signaling may indicate dormancy or inactivation of the second cell, but is not limited thereto, and the first timer of the second cell times out and the second cell enters an inactive state, or The second timer of the BWP of the second cell may time out, and the first target BWP of the second cell may enter an inactive state. Here, the first timer may be a cell inactive timer, and the second timer may be a BWP inactive timer of the first target BWP. Specifically, the embodiments of the present application are not limited.

In the second scheduling configuration, control information in a common search space (CSS) of the second cell can self-schedule the second cell, and the first cell can schedule the second cell. will be. That is, CSS self-scheduling of the second cell deactivated in the second scheduling configuration is activated.

In one possible implementation manner, if the scheduling configuration is the second scheduling configuration and also satisfies the first condition, the control information in the CSS of the second cell may schedule the second cell, that is, the CSS of the second cell. The control information in the CSS can schedule by itself, or the second cell can only be scheduled by the control information in the CSS of the second cell. Here, when the first condition is satisfied, the first cell cannot schedule the second cell. Therefore, in this possible implementation manner, when the first condition is satisfied, the second cell can be scheduled only through the control information in the CSS of the second cell. Here, the control information may be at least one of DCI, MAC CE, PDCCH, or RRC.

In the third scheduling configuration, CSS of the second cell and control information in a UE-specific search space (USS) can schedule the second cell, and the first cell determines the second cell. that can be scheduled. That is, the CSS and USS of the second cell in the third scheduling configuration perform self-scheduling.

In one possible implementation, if the scheduling configuration is the second scheduling configuration, if the first condition is satisfied, the control information (eg, PDCCH or DCI) in the CSS and USS of the second cell is used to schedule the second cell. That is, the control information in CSS and USS of the second cell can perform scheduling by itself, or the second cell can be scheduled only by the control information in CSS and USS of the second cell. Here, when the first condition is satisfied, since the first cell cannot schedule the second cell, in a corresponding possible implementation, when the first condition is satisfied, the second cell only uses the CSS and USS of the second cell. Scheduling can be performed only through control information in

In one possible implementation, when determining the target mapping method according to the scheduling configuration of the first cell and/or the second cell, according to the mapping order, the control unit of the first cell and/or the second cell in one scheduling time unit. Mapping can proceed. Here, the mapping order includes at least one of the following (1) to (3).

(1) First, a control unit that the target cell schedules itself is mapped onto a physical control resource of the target cell, and then a control unit that the target cell schedules other cells is mapped, and the target cell is the first cell. or the second cell.

(2) Mapping is performed in order of control unit identifiers from large to small or from small to large.

(3) First, a public control unit (eg CSS) is mapped on the physical control resource of the target cell, and then a dedicated control unit (eg USS) of the terminal is mapped again.

Here, one scheduling time unit may be one occasion, one span, or one slot, and the embodiments of the present application are not specifically limited.

S212: Information is transmitted according to the target blind detection budget and/or the target mapping method.

After determining the target blind detection budget and/or the target mapping method according to the scheduling configuration of the first cell and/or the second cell of the UE, information is transmitted according to the corresponding target blind detection budget and/or mapping method. For example, in the network-side device, the blind detection quantity may be configured for the terminal according to the target blind detection budget, and the terminal performs blind detection according to the target blind detection budget to obtain scheduling information for each cell. can be obtained. and/or the network-side device may map the control unit of the first cell and/or the second cell to the physical control resource according to the target mapping method, and the terminal detects on the corresponding physical control resource according to the target mapping method. can proceed.

In an embodiment of the present application, the control unit includes, but is not limited to, a quantity of at least one of a search space (SS), a PDCCH, and a control channel element (CCE).

Through the technical solution according to the embodiment of the present application, when the second cell of the UE can be scheduled by the first cell, the UE's target blind detection budget according to the scheduling configuration of the first cell and/or the second cell. and/or determining a target mapping method, and then proceeding with information transmission according to the target blind detection budget and/or the target mapping method, and target blinds of the terminal according to the scheduling configuration of the first cell and/or the second cell. Determining the detection budget and/or target mapping scheme, proceeding with blind detection budget or mapping without considering the configuration situation of Pcell and/or Scell, which affects PDCCH capacity and scheduling efficiency because some blind detection numbers cannot be used. Avoid problems.

Below, the determination of the target blind detection budget and the target mapping method in the embodiments of the present application will be described according to the case where the scheduling configuration is the first scheduling configuration, the second scheduling configuration, and the third scheduling configuration, respectively. .

A. The scheduling configuration is a first scheduling configuration

In one possible implementation, when at least one of the following (1) to (4) is satisfied, the communication device may determine a scheduling configuration as the first scheduling configuration.

(1) transmits first control information, the first control information instructs the second cell or the second cell group to be dormant, and the second cell group is the cell group where the second cell is located am.

Here, the first control information instructs the second cell or the second cell group to be dormant, and the second cell group is a cell group in which the second cell is located.

For example, the first control information may be control information of the second cell, that is, instructs the second cell or the second cell group to be dormant through dormancy indication indicated by the control information of the second cell. and; and/or the second control information may be control information of the first cell, that is, instructs the second cell or the second cell group to be dormant through dormancy indication indicated by the control information of the first cell. .

Here, the first control information is downlink control information (DCI), control information transmitted through a media access control (MAC) control element (Control Unit, CE), or radio resource control (Radio Resource Control (RRC) including control information constituted by signaling, but is not limited thereto.

In an embodiment of the present application, a first cell may schedule a second cell, and in this case, through a protocol agreement or network-side configuration, a) support indicating dormancy indication only through control information of the first cell (could) do; b) supports (and can) indicate dormancy indication only through the control information of the second cell; c) At the same time, the control information of the first cell indicating the dormancy indication in the control information of the second cell supports (can do) the indication of the dormancy indication. The communication device may transmit the cell of the first control information according to a protocol agreement or a network-side configuration.

In a possible implementation manner, if the communication device is a network-side device, sending the first control information indicates that the network-side device sends the first control information to the terminal; if the communication device is a terminal, sending the first control information Transmitting control information indicates that the terminal receives the first control information.

(2) The second cell is deactivated.

For example, the second cell deactivation timer is not configured, the second cell deactivation timer times out, or the second cell deactivation is instructed through MAC CE, RRC, or DCI.

In a corresponding possible implementation, when the second cell deactivation is instructed through MAC CE, RRC or DCI, if the communication device is a network-side device, a deactivation command is transmitted to the terminal to instruct the second cell to be deactivated. can If the communication device is a terminal, it may receive a deactivation command transmitted by the network side.

(3) The bandwidth part (BWP) of the second cell is converted to a BWP that cannot schedule the second cell.

For example, the BWP that can schedule the second cell is switched to the BWP that cannot schedule the second cell.

(4) BWP of the second cell is deactivated.

For example, the second cell does not configure a BWP inactive timer or the BWP inactive timer of the second cell expires.

In the above possible implementation, when satisfying any one of (1) to (4) above, the communication device considers the current configuration to be the first scheduling configuration, or switches to the first scheduling configuration. In this case, the second scheduling configuration Either the cell is considered unable to schedule itself (but can schedule other cells), or the secondary cell is considered unable to schedule any cell. Here, when the above (1) or (2) is satisfied, the second cell is in a dormant or inactive state, the terminal cannot monitor the control information of the network side in the second cell, and also the control unit in the second cell ( control element), the communication device considers that the secondary cell cannot schedule any cell. When the above (3) or (4) is satisfied, since the BWP of the second cell cannot schedule the BWP of the second cell, but the second cell can monitor the control information of the network side, the second cell It cannot schedule itself, but it can schedule other cells.

Here, the fact that the second cell cannot schedule itself means that the network-side device does not transmit control information for scheduling the second cell in the second cell, and the terminal monitors control information for scheduling the second cell in the second cell. It is not necessary to do this, but the network-side device may schedule the control information for scheduling other cells in the second cell, and the terminal should monitor the control information for scheduling other cells in the second cell; The fact that the second cell cannot schedule any cell means that the network-side device does not transmit control information for scheduling any cell in the second cell, and the UE needs to monitor control information for scheduling any cell in the second cell. indicates that there is no

When the above (1) to (4) are satisfied, some blind detection numbers corresponding to the second cell may not be used, and it may be considered to re-allocate some blind detection capabilities of the terminal. For example, if the second cell cannot schedule itself, the second cell may reduce the maximum blind detection number of the control unit that schedules itself; if the second cell cannot schedule any cell, The maximum number of blind detections of the control unit of the second cell may be reduced, and some of the reduced number of blind detections may be allocated to the first cell.

In an embodiment of the present application, when the first cell can schedule the second cell, the search space that the embodiment of the present application considers when determining a target blind detection budget and/or the target mapping scheme is:

1) an SS that self-schedules in the second cell (here, the corresponding SS may be CSS or USS, and both CSS and USS may exist);

2) SS in which the first cell schedules the second cell;

3) The first cell includes, but is not limited to, at least one of SSs scheduling other cells (referred to as “third cell” in this application for convenience of classification). Here, the SS for self-scheduling of the first cell and/or the SS for scheduling of the third cell, the SS for self-scheduling of the first cell and the SS for scheduling of the third cell may be the same or different, The SS in which the first cell schedules other cells may include CSS or only USS.

In an embodiment of the present application, optionally, the third cell may be a cell of a different type from the first cell, for example, both the third cell and the first cell are secondary cells.

In the embodiments of the present application, at least one set of maximum blind detection parameters may be configured for each UE, and each set of maximum blind detection parameters includes:

1) the maximum blind detection number P of the control unit of the second cell;

2) the maximum blind detection number P-self of the control unit that the second cell self-schedules;

3) maximum blind detection number CR of the control unit of the second cell scheduled by the first cell;

4) the maximum blind detection number S of the control unit of the first cell;

5) the maximum blind detection number S-self of the control unit that the first cell self-schedules;

6) the maximum blind detection number S-other of the control unit of the third cell scheduled by the first cell;

7) the maximum blind detection number S-selfandother of the control unit for which the first cell schedules itself and the third cell;

8) At least one of the maximum blind detection numbers T of a joint between the first cell and the control unit of the first cell may be configured.

If the scheduling configuration below is the first scheduling configuration, a description will be made on how to determine the target blind detection budget and the target mapping scheme of the terminal.

(A) Determination of target blind detection budget

In one possible implementation, when satisfying any one of the above (1) to (4), the first cell schedules the second cell (ie, the first cell schedules the SS of the second cell) of the control unit Blind detection can be assigned to the second cell's blind detection share, i.e., CR as part of P.

Therefore, in the above possible implementation, determining the target blind detection budget in S210, if the scheduling configuration is the first scheduling configuration, the first blind detection upper limit is the maximum of the control unit of the second cell. determining that it is equal to a maximum blind detection quantity, wherein the first blind detection upper limit is a maximum blind detection quantity of a control unit for which the first cell schedules the second cell; and/or if the scheduling configuration is the first scheduling configuration, determine that a second blind detection upper limit is equal to 0, and the second maximum blind detection number is a maximum blind detection number of a control unit that the second cell self-schedules. include that

In this possible implementation, the maximum blind detection number of the control unit scheduling the second cell in the first cell is the maximum blind detection number of the control unit of the second cell, that is, when the second cell cannot schedule any cell. , the maximum number of blind detections allocated to the second cell in advance as the maximum number of blind detections of the control unit for scheduling the second cell by the first cell, so that the blind detection capability of the terminal can be sufficiently used. and/or when the second cell cannot schedule itself, the maximum number of blind detections of the control unit that the second cell schedules itself is set to 0, so that the second cell cannot schedule itself. It is assigned to 2 cells to prevent a problem in which blind detection numbers cannot be used for self-scheduling.

In another possible implementation manner, in S210, determining the target blind detection budget, if the scheduling configuration is the first scheduling configuration, uses a first maximum blind detection parameter corresponding to the first scheduling configuration to determine the target blind detection budget. It may include determining a blind detection budget. In this possible implementation, multiple sets of maximum blind detection parameters may be configured for one terminal, and if the scheduling configuration is the first scheduling configuration, the second maximum blind detection parameter corresponding to the first scheduling configuration is used. to determine the target blind detection budget of the terminal.

In the possible implementation manner, optionally, the terminal may also configure a second maximum blind detection parameter, in this case, the first maximum blind detection parameter and the second maximum blind detection parameter are: the first upper limit of blind detection in the maximum blind detection parameters is greater than the upper limit of first blind detection in the second maximum blind detection parameters; the first blind detection upper limit is the maximum blind detection number of a control unit for which the first cell schedules the second cell; The third upper limit of blind detection in the first maximum blind detection parameter is greater than the upper limit of third blind detection in the second maximum blind detection parameter, and the third upper limit of blind detection is the maximum number of blind detections of the control unit of the first cell. satisfies at least one

That is, in the above possible implementation manner, the maximum blind detection number CR' of the control unit for which the first cell in the first maximum blind detection parameter schedules the second cell is the first cell in the second maximum blind detection parameter. greater than the maximum blind detection number CR of the control unit scheduling the second cell; The maximum blind detection number S' of the control unit of the first cell in the first maximum blind detection parameter is greater than the maximum blind detection number S of the control unit of the first cell in the second maximum blind detection parameter.

In other words, in a corresponding possible implementation, the first cell configures a more blind detection number than the second maximum blind detection number for the control unit scheduling the second cell in the first maximum blind detection parameter, or the first maximum blind detection number. Configure a blind detection number greater than the second maximum blind detection number for the control unit of the first cell in the blind detection parameter. That is, in a corresponding possible implementation, since the second cell cannot schedule itself or the second cell cannot schedule any cell under the first scheduling configuration, the blind detection number configured to correspond to the second cell is Not used. Therefore, the capacity of the downlink control channel can be improved by adding the maximum number of blind detections corresponding to the control unit in which the first cell schedules the second cell and/or the maximum number of blind detections corresponding to the control unit of the first cell. can

In the above selectable implementation, the second maximum blind detection parameter may be the second cell itself scheduling, or the second cell itself scheduling and also scheduling other cells, and the first cell may schedule itself It may be a maximum blind detection parameter used when scheduling the second cell, and the embodiment of the present application is not specifically limited.

In another possible implementation, when satisfying any one of (1) to (4) above, the first cell schedules the second cell (ie, the first cell schedules the SS of the second cell) of the control unit It is possible to make blind detection belong to the blind detection share of the first cell, that is, let CR be a part of S.

Therefore, in the above possible implementation manner, determining the target blind detection budget in S210, if the scheduling configuration is the first scheduling configuration, it is determined that the fourth blind detection upper limit is 0, and the fourth blind detection upper limit is The method may further include determining the maximum number of blind detections of the control unit of the second cell, that is, the maximum number of blind detections of the control unit of the second cell as 0. In other words, in this possible implementation, if any one of the conditions (1) to (4) above is satisfied, since the second cell is considered to be unable to schedule any cell, the maximum blind detection of the control unit of the second cell By setting the number to 0, waste of the maximum blind detection capability of the terminal is prevented.

Alternatively, in the above possible implementation, determining the target blind detection budget in S210 may include determining the target blind detection budget using a third maximum blind detection parameter corresponding to the first scheduling configuration. In this possible implementation, multiple sets of maximum blind detection parameters may be configured for one terminal, and if the scheduling configuration is the first scheduling configuration, the third maximum blind detection parameter corresponding to the first scheduling configuration is used. to determine the target blind detection budget of the terminal.

In the above possible implementation manner, optionally, the terminal may also have a fourth maximum blind detection parameter configured, in this case, the third maximum blind detection parameter and the fourth maximum blind detection parameter are as follows (1 ) to (5) can be satisfied.

(1) a fourth blind detection upper limit in the third maximum blind detection parameter is 0, and the fourth blind detection upper limit is a maximum blind detection number of the control unit of the second cell; In other words, the maximum blind detection number P' of the control unit of the second cell in the third maximum blind detection parameter is zero.

Since the secondary cell cannot schedule any cell, the maximum blind detection number of the control unit of the secondary cell in the third maximum blind detection parameter is set to 0 to avoid wasting the maximum blind detection capability of the terminal.

(2) the third upper limit of blind detection in the third maximum blind detection parameter is greater than the upper limit of fourth blind detection in the fourth maximum blind detection parameter, and the third upper limit of blind detection is the maximum blind detection limit of the control unit of the first cell. is the number of detections. In other words, the maximum blind detection number S' of the control unit of the first cell in the third maximum blind detection parameter is greater than the maximum blind detection number S of the control unit of the first cell in the fourth maximum blind detection parameter.

In this possible implementation, since the blind detection of the control unit scheduling the second cell by the first cell is assigned to the blind detection share of the first cell, the maximum number of blind detections of the control unit of the first cell should be increased.

(3) a fifth blind detection upper limit in the third maximum blind detection parameter is greater than a fifth blind detection upper limit in the fourth maximum blind detection parameter, and the fifth blind detection upper limit is a self-scheduled control unit of the first cell is the maximum number of blind detections of In other words, the maximum blind detection number S-self' of the control unit for self-scheduling by the first cell in the third maximum blind detection parameter is the self-scheduling control of the first cell in the fourth maximum blind detection parameter. The unit's maximum blind detection count is greater than S-self.

Since the second cell cannot schedule any cell, the blind detection budget corresponding to the second cell can be allocated again on the first cell's own scheduling. Therefore, if the scheduling configuration is the first scheduling configuration, the maximum blind detection number of the control unit that the first cell self-schedules in the third maximum blind detection parameter corresponding to the first scheduling configuration is the maximum blind detection number in the fourth maximum blind detection parameter. It can be set larger than the maximum blind detection number of a control unit that one cell itself schedules.

(4) a first blind detection upper limit in the third maximum blind detection parameter is greater than a sixth blind detection upper limit in the fourth maximum blind detection parameter, and the first blind detection upper limit is such that the first cell detects the second cell This is the maximum number of blind detections of the scheduling control unit. In other words, the maximum blind detection number CR' of the control unit for which the first cell in the third maximum blind detection parameter schedules the second cell is the first cell in the fourth maximum blind detection parameter. is greater than the maximum blind detection number CR of the control unit scheduling

Since the second cell cannot schedule any cell, the blind detection budget corresponding to the second cell can be allocated again on the first cell's own scheduling. Therefore, if the scheduling configuration is the first scheduling configuration, the maximum blind detection number of the control unit for which the first cell schedules the second cell in the third maximum blind detection parameter corresponding to the first scheduling configuration is the maximum blind detection number in the fourth maximum blind detection parameter. The first cell may be set to be greater than the maximum blind detection number of the control unit scheduling the second cell.

(5) a sixth blind detection upper limit in the third maximum blind detection parameter is greater than a sixth blind detection upper limit in the fourth maximum blind detection parameter, and the sixth blind detection upper limit is such that the first cell is different from the first cell; This is the maximum blind detection number of the control unit scheduling the third cell. In other words, the maximum blind detection number S-selfandother' of the control unit for which the first cell in the fourth maximum blind detection parameter schedules the first cell and the third cell is the first cell in the fourth maximum blind detection parameter. cell is greater than the maximum blind detection number S-selfandother of the control unit scheduling the first cell and the third cell.

Since the second cell cannot schedule any cell, the blind detection budget corresponding to the second cell can be allocated again on the first cell's own scheduling. Therefore, if the scheduling configuration is the first scheduling configuration, the maximum blind detection number of the control unit scheduling the first cell and the third cell for the first cell in the third maximum blind detection parameter corresponding to the first scheduling configuration is 4 The first cell in the maximum blind detection parameter may be set to be larger than the maximum blind detection number of a control unit scheduling the first cell and the third cell.

In the above selectable implementation, the fourth maximum blind detection parameter may be that the second cell may schedule itself, or the second cell may schedule itself and may also schedule other cells, and the first cell may schedule itself. It may be a maximum blind detection parameter used when scheduling the second cell, and the embodiment of the present application is not specifically limited.

In another possible implementation, the blind detection of the control unit in which the first cell schedules the second cell may also be allocated to the joint blind detection share of the first cell and the second cell, i.e., CR is a part of T.

Therefore, in the above possible implementation manner, determining the target blind detection budget in S210 may include any one of the following (1) to (3).

(1) if the scheduling configuration is the first scheduling configuration, determining that a first blind detection upper limit is equal to an associated maximum blind detection number of control units of the first cell and the second cell; is the maximum blind detection number of the control unit for which the first cell schedules the second cell.

(2) if the scheduling configuration is the first scheduling configuration, determining that a seventh blind detection upper limit is equal to an associated maximum blind detection number of control units of the first cell and the second cell, and the seventh blind detection upper limit is the maximum blind detection number of the control unit for which the first cell schedules the first cell and the second cell.

(3) if the scheduling configuration is the first scheduling configuration, determine that an eighth blind detection upper limit is equal to an associated maximum blind detection number of control units of the first cell and the second cell, and the eighth blind detection upper limit is the maximum blind detection number of a control unit for which the first cell schedules the second cell, the first cell, and the third cell.

Alternatively, in the above possible implementation, determining the target blind detection budget in S210, if the scheduling configuration is the first scheduling configuration, uses a fifth maximum blind detection parameter corresponding to the first scheduling configuration to determine the target blind detection budget. It may include determining a blind detection budget. In this possible implementation, multiple sets of maximum blind detection parameters may be configured for one terminal, and if the scheduling configuration is the first scheduling configuration, the fifth maximum blind detection parameter corresponding to the first scheduling configuration is used. to determine the target blind detection budget of the terminal.

In the above possible implementation manner, optionally, the terminal may also have a sixth maximum blind detection parameter configured, in this case, the third maximum blind detection parameter and the fourth maximum blind detection parameter are as follows (1 ) to (2) can be satisfied.

(1) a first blind detection upper limit of the fifth maximum blind detection parameter is greater than a first blind detection upper limit of the sixth maximum blind detection parameter, and the first blind detection upper limit is such that the first cell detects the second cell; This is the maximum number of blind detections of the scheduling control unit. In other words, the maximum blind detection number CR' of the control unit for which the first cell in the fifth maximum blind detection parameter schedules the second cell is the first cell in the sixth maximum blind detection parameter. is greater than the maximum blind detection number CR of the control unit scheduling

Since the second cell cannot schedule any cell, the blind detection budget corresponding to the second cell can be allocated again on the first cell's own scheduling. Therefore, if the scheduling configuration is the first scheduling configuration, the maximum blind detection number of the control unit for which the first cell schedules the second cell in the fifth maximum blind detection parameter corresponding to the first scheduling configuration is the maximum blind detection number in the sixth maximum blind detection parameter. The first cell may be set to be greater than the maximum blind detection number of the control unit scheduling the second cell.

(2) a ninth blind detection upper limit in the fifth maximum blind detection parameter is greater than or less than a ninth blind detection upper limit in the sixth maximum blind detection parameter, and the ninth blind detection upper limit is determined by the first cell and the second blind detection upper limit. It is the maximum blind detection number of associations of the cell's control unit. In other words, the joint maximum blind detection number T' of the control unit of the first cell and the second cell in the fifth maximum blind detection parameter is the control unit of the first cell and the second cell in the sixth maximum blind detection parameter. Greater than or less than the combined maximum blind detection number T of units.

Since the second cell cannot schedule any cell, the blind detection budget corresponding to the second cell can be allocated again on the first cell's own scheduling. Therefore, if the scheduling configuration is the first scheduling configuration, the joint maximum blind detection number of the control units of the first cell and the second cell among the fifth maximum blind detection parameters corresponding to the first scheduling configuration is the sixth maximum blind detection parameter. may be set to be greater than the maximum blind detection number associated with the control unit of the first cell and the second cell in Or, since the second cell cannot schedule any cell, one possible case is that the data to be scheduled is reduced, so in order to effectively allocate the maximum blind detection capability of the terminal, in this case, the first cell and the second cell The maximum combined blind detection number of the control unit of the cell may be lowered.

In the above selectable implementation, the sixth maximum blind detection parameter may be that the second cell may schedule itself, or the second cell may schedule itself and may also schedule other cells, and the first cell may schedule itself. It may be a maximum blind detection parameter used when scheduling the second cell, and the embodiment of the present application is not specifically limited.

In each of the possible implementation methods, the determined target blind detection budget may be a blind detection budget of any one of the following (1) to (8) of the terminal.

(1) within a first predetermined time or after a second predetermined time when the scheduling configuration is determined as the first scheduling configuration;

For example, within a first predetermined time or after a second predetermined time when the second cell or the second cell group is instructed to be dormant by the first control information.

(2) Before transmitting second control information (the second control information indicates that the second cell or second cell group is non-dormant, and the second cell group is a cell group where the second cell is located)

Here, similar to the first control information, the second control information may be DCI, and may also be control information indicated by MAC CE or RRC, and is not specifically limited in this embodiment.

In other words, in this possible implementation, if the scheduling configuration is determined to be the first scheduling configuration, all information transmission proceeds using the determined target blind detection budget unless the second control information is transmitted.

(3) before the second cell is activated

In other words, in this possible implementation, if the scheduling configuration is determined to be the first scheduling configuration, as long as the second cell is not activated, information transmission proceeds using the determined target blind detection budget.

(4) before the second cell is reconstructed

In other words, in this possible implementation, if the scheduling configuration is determined to be the first scheduling configuration, information transmission proceeds using the determined target blind detection budget, unless the second cell is reconfigured. After the second cell is reconfigured, a corresponding scheduling configuration may be determined according to the state of the second cell after reconfiguration.

(5) Before the first timer of the second cell is started

In other words, in this possible implementation, if the scheduling configuration is determined to be the first scheduling configuration, as long as the first timer of the second cell is not running, information transmission proceeds using the determined target blind detection budget.

Here, the first timer may be a cell inactive timer. Optionally, after the first timer runs, a second cell deactivation countdown is entered, and after the first timer times out, the second cell is deactivated.

(6) Before the first target BWP of the second cell is activated (the first target BWP is a BWP capable of scheduling the second cell)

In other words, in this possible implementation, if the scheduling configuration is determined to be the first scheduling configuration, as long as the first target BWP is not activated, all information transmission proceeds using the determined target blind detection budget.

(7) Before the first target BWP of the second cell is reconstructed

In other words, in this possible implementation, if the scheduling configuration is determined as the first scheduling configuration, unless the first target BWP is reconfigured, information transmission proceeds using the determined target blind detection budget.

(8) Before the second timer of the first target BWP of the second cell is started

In other words, in this possible implementation, if the scheduling configuration is determined to be the first scheduling configuration, as long as the second timer of the first target BWP of the second cell is not running, all information is obtained using the determined target blind detection budget. proceed with the transmission.

Here, the second timer may be a BWP inactive timer. Optionally, after the second timer runs, a countdown for deactivating the first target BWP of the second cell is entered, and after the first timer times out, the first target BWP of the second cell is deactivated.

In one possible implementation, the target mapping method determined in (B) below may also be applied to the time, but may not be applied only to the time, and is not specifically limited in this embodiment.

(B) Determination of target mapping method

In one possible implementation, when the scheduling configuration is the first scheduling configuration, the blind detection of the control unit in which the first cell schedules the second cell (ie, the first cell schedules the SS of the second cell) is performed in the second cell. can be assigned to the blind detection stake of , i.e., with CR as part of P.

Therefore, in the above possible implementation manner, determining the target mapping scheme according to the scheduling configuration of the first cell and/or the second cell in S210, if the scheduling configuration is the first scheduling configuration, determines the mapping scheme in one scheduling time unit. When mapping the control unit of the second cell, a control unit other than self-scheduled by the second cell is mapped onto the physical control resource of the second cell, and/or onto the physical control resource of the first cell. The first cell may include mapping a control unit that schedules the second cell.

In other words, when the control unit of the second cell is mapped in one scheduling time unit, control units other than the control unit that the second cell itself schedules are mapped.

For example, the search space in which the second cell itself schedules is SS#0/1/2/3/5, the search space in which the first cell schedules the second cell is SS#4, and the second cell The search space for scheduling the third cell is SS#5/6, and if the cell group where the second cell or the first cell is located in the second cell or the first cell is dormant, or the second cell is In case of inactivation, or when switching occurs in the BWP (capable of scheduling the second cell) of the second cell, or inactivation of the BWP (capable of scheduling the second cell) of the second cell, the mapping sequence According to the (sequence), SS#4 is first mapped on the physical control resources of the first cell, and then SS#5/6 is mapped on the physical control resources of the second cell.

In the above possible implementation, within one scheduling time unit, the total quantity of mapped control units does not exceed the maximum blind detection number of the second cell, that is, the physical control resources of the first cell and/or The total number of control units mapped on the physical control resources of the second cell does not exceed the maximum blind detection number of the second cell. That is, in one scheduling time unit, the maximum blind detection number of the second cell is mapped to the nearest control unit, and if there is a control unit that has not yet been mapped, mapping is not continued.

Here, the maximum number of blind detections of the second cell may be determined according to the target blind detection budget. It is not specifically limited in this application.

In another possible implementation, when the scheduling configuration is the first scheduling configuration, the blind detection of the control unit in which the first cell schedules the second cell (i.e., the first cell schedules the second cell's SS) is performed on the first cell. can be assigned to the blind detection stake of , i.e., with CR as part of S.

Therefore, in the above possible implementation, within one scheduling time unit, the total number of control units mapped on the physical control resources of the first cell and/or the physical control resources of the second cell is the maximum blind of the first cell. Do not exceed the number of detections. That is, in one scheduling time unit, the maximum blind detection number of the first cell is mapped to the nearest control unit, and if there is a control unit that has not yet been mapped, mapping is not continued.

For example, the search space in which the first cell itself schedules is SS#6, the search space in which the first cell schedules the second cell is SS#5, and if the second cell or the second cell in the first cell Or, the cell group in which the second cell is located is dormant, or the second cell is inactive, or a transition occurs in the BWP of the second cell (which can schedule the second cell), or the second cell ( When BWP inactivation (which can schedule 2 cells) is indicated, when mapping the search space on the physical control resource of the first cell, SS#5 is first mapped, and then SS#6 is mapped.

In another possible implementation, the blind detection of the control unit in which the first cell schedules the second cell may also be allocated to the joint blind detection share of the first cell and the second cell, i.e., CR is a part of T.

Therefore, in a possible implementation manner, determining the target mapping method according to the scheduling configuration of the first cell and/or the second cell in S210, if the scheduling configuration is the first scheduling configuration, in one scheduling time unit When mapping a control unit of a control unit of a second cell and/or a control unit of the first cell, mapping a control unit self-scheduled by the first cell onto a physical control resource of the first cell, and /or mapping a control unit for scheduling the second cell by the first cell onto a physical control resource of the first cell.

In the above possible implementation manner, since the first cell scheduling the second cell belongs to the joint budget of the control units of the first cell and the second cell, and the second cell cannot schedule itself at least, one scheduling time When the unit performs the mapping of scheduling the second cell and/or the mapping of the control unit of the second cell, the first cell maps the control unit scheduling itself and/or the first cell schedules the second cell.

In the above possible implementation manner, since scheduling of the second cell by the first cell belongs to the joint budget of the control units of the first cell and the second cell, within one scheduling time unit, the total number of control units mapped to the above The joint maximum blind detection number of the joint control unit of the first unit and the control unit of the second unit is not exceeded.

B. If the scheduling configuration is the second scheduling configuration or the third scheduling configuration

In one possible implementation, if the scheduling configuration is the second scheduling configuration or the third scheduling configuration, if the first condition is satisfied, it is determined that the first cell cannot schedule the second cell, or the first cell has no The cell also determines that it cannot be scheduled.

In each of the above possible implementations of the embodiments of the present application, the first condition includes, but is not limited to, at least one of the following (1) to (4).

(1) Third control information is transmitted, the third control information instructs the first cell or the first cell group to be dormant, and the first cell group is a cell group in which the first cell is located.

For example, the third control information may be control information of the first cell, that is, instructs the first cell or the first cell group to be dormant through dormancy indication indicated by the control information of the first cell. and; and/or the third control information may be control information of the second cell, that is, instructs the first cell or the first cell group to be dormant through dormancy indication indicated by the control information of the second cell. .

Here, the third control information includes, but is not limited to, control information transmitted through DCI and MAC CE or control information constituted by RRC signaling.

In an embodiment of the present application, a first cell may schedule a second cell, and in this case, through a protocol agreement or network-side configuration, a) support indicating dormancy indication only through control information of the first cell (could) do; b) supports (and can) indicate dormancy indication only through the control information of the second cell; c) At the same time, the control information of the first cell indicating the dormancy indication in the control information of the second cell supports (can do) the indication of the dormancy indication. The communication device may transmit cells of the third control information according to a protocol agreement or a network-side configuration.

(2) The first cell is deactivated.

For example, the deactivation timer of the first cell is not configured, the deactivation timer of the first cell expires, or the deactivation of the first cell is instructed through MAC CE, RRC, or DCI.

(3) The BWP of the first cell is converted to a BWP that cannot schedule the second cell.

For example, a BWP capable of scheduling the second cell of the first cell is converted into a BWP that cannot schedule the second cell.

(4) BWP of the first cell is deactivated.

For example, the first cell does not configure a BWP inactive timer or the BWP inactive timer of the first cell expires.

When any one of the above first conditions is satisfied, it is considered that the first cell cannot schedule the second cell, but can schedule itself and other cells, or also that the first cell cannot schedule any cell. can be considered Here, when the above (1) or (2) is satisfied, the first cell is in a dormant or inactive state, the terminal cannot monitor the control information of the network side in the first cell, and also the control unit in the first cell Since it cannot schedule, the communication device considers that the first cell cannot schedule any cell. When the above (3) or (4) is satisfied, the BWP of the first cell cannot schedule the BWP of the second cell, but since the first cell can monitor the control information of the network side, the first cell It cannot schedule the second cell, but it can schedule itself and other cells.

Therefore, some blind detection numbers corresponding to the first cell may not be used, and it may be considered to re-allocate some blind detection capabilities of the UE. For example, if the first cell cannot schedule the second cell, the first cell may reduce the maximum blind detection number of the control unit scheduling the second cell, and if the first cell schedules no cell If not, the maximum blind detection number of the control unit of the first cell may be reduced, and some of the reduced blind detection numbers may be allocated to the second cell. Therefore, it is necessary to reallocate the terminal's blind detection budget and/or to adjust the mapping method. In this case, descriptions will be made on how to determine the target blind detection budget and the target mapping scheme of the terminal.

(A) target blind detection

In one possible implementation, if the first cell determines that it cannot schedule the second cell, or if the first cell determines that it cannot schedule any cell, the first cell controls scheduling the second cell. The unit may be the blind detection budget of the second cell.

Therefore, in the above possible implementation manner, determining the target blind detection budget according to the scheduling configuration of the first cell and/or the second cell in S210 determines that the first blind detection upper limit is equal to 0; the blind detection upper limit is the maximum number of blind detections of a control unit for which the first cell schedules the second cell; and/or determining that the second upper limit of blind detection is equal to the maximum number of blind detections of the control unit of the second cell, and the second upper limit of blind detection is the maximum number of blind detections of the control unit that the second cell itself schedules. can include

In the above possible implementation manner, since the first cell cannot schedule the second cell, that is, because the number of control units for the first cell to schedule the second cell is 0, the target blind detection budget of the terminal The sixth maximum number of blind detections (that is, the maximum number of blind detections of a control unit in which the first cell schedules the second cell) may be set to 0. Also, since the control unit for scheduling the second cell in the first cell is the blind detection budget of the second cell, and the number of control units for scheduling the second cell in the first cell is 0, the seventh in the target blind detection budget Physical resources can be sufficiently used by setting the maximum number of blind detections (that is, the maximum number of blind detections of the control unit that the second cell itself schedules) to the maximum number of blind detections of the control unit of the first cell.

Optionally, in the above possible implementation manner, when the control unit for scheduling the second cell by the first cell is the blind detection budget of the second cell, according to the scheduling configuration of the first cell and/or the second cell, the target blind Determining the detection budget may include determining the target blind detection budget using a seventh maximum blind detection parameter. That is, the target blind detection budget of the terminal is set using the seventh maximum blind detection parameter. In the selectable implementation scheme, multiple sets of maximum blind detection numbers may be configured for the terminal, and the seventh maximum blind detection number corresponds to the target state of the terminal, wherein the scheduling configuration is the second scheduling configuration with the corresponding target state. or a third scheduling configuration, which also satisfies the first condition.

In the above selectable implementation, an eighth maximum blind detection parameter may also be configured, wherein the seventh maximum blind detection parameter and the eighth maximum blind detection parameter satisfy at least one of the following (1) and (2): satisfy

(1) a second blind detection upper limit in the seventh maximum blind detection parameter is greater than a second blind detection upper limit in the eighth maximum blind detection parameter, and the second blind detection upper limit is a self-scheduled control unit of the second cell is the maximum number of blind detections of In other words, the maximum blind detection number P-self' of the control unit for self-scheduling by the second cell in the seventh maximum blind detection parameter is the self-scheduling control of the second cell in the eighth maximum blind detection parameter. The unit's maximum blind detection count is greater than P-self.

Since the control unit for scheduling the second cell in the first cell is the blind detection budget for the second cell, and the number of control units for scheduling the second cell in the first cell is 0, the blind detection budget for the control unit in the first cell is 0. Part of the detection budget may be allocated again to a control unit that the second cell itself schedules. Therefore, in this implementation, the maximum blind detection number of the control unit self-scheduled by the second cell in the seventh maximum blind detection parameter is the maximum blind detection number of the control unit self-scheduled by the second cell in the eighth maximum blind detection parameter. greater than the number of detections.

(2) a fourth blind detection upper limit in the seventh maximum blind detection parameter is greater than a fourth blind detection upper limit in the eighth maximum blind detection parameter, and the fourth blind detection upper limit is the maximum blind detection limit of the control unit of the second cell. is the number of detections. In other words, the maximum blind detection number P' of the control unit of the second cell in the seventh maximum blind detection parameter is greater than the maximum blind detection number P of the control unit of the second cell in the eighth maximum blind detection parameter.

Since the control unit for scheduling the second cell in the first cell is the blind detection budget for the second cell, and the number of control units for scheduling the second cell in the first cell is 0, the blind detection budget for the control unit in the first cell is 0. A part of the detection budget may be allocated again to the control unit of the second cell. Therefore, in this implementation, the maximum blind detection number of the control unit of the second cell in the seventh maximum blind detection parameter is greater than the maximum blind detection number of the control unit of the second cell in the eighth maximum blind detection parameter.

In the above possible implementation, the eighth maximum blind detection parameter may be the target blind detection in the normal case of the terminal, for example, the first cell may schedule the second cell, and the second cell may schedule itself. can do.

Using the above possible implementation, since the first cell can no longer schedule the second cell at this time, the second cell can only schedule itself using the control information of the second cell itself, so that the second cell The maximum blind detection number of the control unit scheduling itself may be adjusted, for example, the maximum blind detection number of the control unit scheduling itself in the second cell is the maximum blind detection number of the control unit of the second cell. ie, allowing more secondary cells to schedule themselves, making full use of the number of blind detections in the idle state.

Optionally, what the second cell self-schedules (or a control unit that the second cell self-schedules) may include the UE's CSS, for example, a group common PDCCH.

In another possible implementation, if the scheduling configuration is the second scheduling configuration or the third scheduling configuration, if the first condition is satisfied, also the first cell scheduling the second cell may be regarded as the budget of the first cell. there is.

Therefore, in the above possible implementation manner, determining the target blind detection budget according to the scheduling configuration of the first cell and/or the second cell,

determining that a first blind detection upper limit is equal to 0, wherein the first blind detection upper limit is a maximum blind detection number of a control unit for which the first cell schedules the second cell;

determining that a fifth blind detection upper limit is equal to a maximum blind detection number of a control unit of the first cell, and that the fifth blind detection upper limit is a maximum blind detection number of a control unit scheduling itself by the first cell;

It is determined that a sixth blind detection upper limit is equal to a maximum number of blind detections of a control unit of the first cell, and the sixth blind detection upper limit is a maximum of a control unit scheduling the first cell and the third cell in the first cell. being the number of blind detections;

It is determined that a third blind detection upper limit is equal to 0, and the third blind detection upper limit includes at least one of a maximum blind detection number of a control unit of the first cell.

Using the above possible implementation, since the first cell can no longer schedule the second cell, the first cell can only schedule cells other than the second cell (e.g., the first cell). The maximum number of blind detections scheduled by the cell itself may be adjusted, for example, the maximum number of blind detections scheduled by the first cell may be configured as the maximum number of blind detections supported by the first cell, That is, more primary cells are allowed to schedule themselves, and the number of blind detections in the idle state is sufficiently used.

In the above possible implementation manner, each term may be combined with each other, for example, the first blind detection upper limit is set to 0, and the fifth blind detection upper limit is set to the maximum blind detection number of the control unit of the first cell. That is, the blind detection budget of the control unit of the first cell is all the blind detection budget that the first cell itself schedules.

Alternatively, the first blind detection upper limit may be set to 0, and the sixth blind detection upper limit may be set to the maximum number of blind detections of the control unit of the first cell, that is, the blind detection budget of the control unit of the first cell may be completely reduced. A blind detection budget in which one cell schedules the first cell and the third cell is assumed. Since the first cell can no longer schedule the second cell, the first cell can only schedule cells other than the second cell (e.g., the first cell itself and/or the third cell, i.e. other cells). , When CA is limited, since the number of cells scheduled by the first cell changes, the maximum blind detection number of S-self and other can be adjusted, for example, the maximum blind detection number of the first cell, that is, more first cells. Cell and tertiary cell scheduling is allowed.

or if the first cell is unable to schedule any cell, the first cell is dormant, or the first cell is inactive, or a transition occurs in the BWP of the first cell (which can schedule the second cell); , or BWP inactivation of the first cell (capable of scheduling the second cell), when the first cell cannot schedule any cell, the maximum blind detection number of the control unit of the first cell is set to 0. can be set to

In the above possible implementation manner, if the first cell scheduling the second cell belongs to the blind detection budget of the first cell, the target blind detection budget is set according to the scheduling configuration of the first cell and/or the second cell. The determining may further include determining a target blind detection budget using the ninth maximum blind detection parameter. That is, the target blind detection budget of the terminal is set using the ninth maximum blind detection parameter. In the selectable implementation method, multiple sets of maximum blind detection numbers may be configured for the terminal, and the ninth maximum blind detection number corresponds to the target state of the terminal, wherein the scheduling configuration is the second scheduling configuration with the corresponding target state. or a third scheduling configuration, which also satisfies the first condition.

Optionally, the terminal may also be configured with a tenth maximum blind detection parameter, wherein the ninth maximum blind detection parameter and the tenth maximum blind detection parameter satisfy at least one of the following.

The fifth blind detection upper limit in the ninth maximum blind detection parameter is greater than the fifth blind detection upper limit in the tenth maximum blind detection parameter, and the fifth blind detection upper limit is the maximum blind detection limit of the control unit self-scheduled by the first cell. is the number of detections. In other words, the maximum blind detection number S-self' of the control unit for self-scheduling by the first cell in the ninth maximum blind detection parameter is the self-scheduling control of the first cell in the tenth maximum blind detection parameter. greater than the unit's maximum blind detection number S-self;

The sixth blind detection upper limit in the ninth maximum blind detection parameter is greater than the sixth blind detection upper limit in the tenth maximum blind detection parameter, and the sixth blind detection upper limit is such that the first cell corresponds to the first cell and the third cell. is the maximum number of blind detections of the control unit that schedules . In other words, the maximum blind detection number S-selfandother' of the control unit for which the first cell in the ninth maximum blind detection parameter schedules the first cell and the third cell is the first cell in the tenth maximum blind detection parameter. cell is greater than the maximum blind detection number S-selfandother of the control unit scheduling the first cell and the third cell.

In the above possible implementation, the tenth maximum blind detection parameter may be the target blind detection in the normal case of the terminal, for example, the first cell may schedule the second cell, and the second cell may schedule itself. can do.

In another possible implementation, scheduling of the second cell by the first cell may also fall within the joint blind detection budget of the control units of the first cell and the second cell.

In the above possible implementation manner, determining the target blind detection budget according to the scheduling configuration of the first cell and/or the second cell is such that the tenth blind detection upper limit is of the control unit of the second cell, the same as that of the first cell. It may be determined that the joint maximum blind detection number is equal to, and the tenth blind detection upper limit may include a maximum blind detection number in which the first cell schedules a control unit other than the second cell. Since the first cell can no longer schedule the second cell, in a corresponding possible implementation, the maximum blind detection number for which the first cell schedules a control unit other than the second cell is defined as the difference between the first cell and the second cell. Set to the maximum number of blind detections associated with the control unit to fully utilize the number of blind detections in the idle state.

In each of the above possible implementation methods, the determined target blind detection budget may be a blind detection budget of any one of the following (1) to (8) of the terminal.

(1) within a third predetermined time or after a fourth predetermined time after determining that the first cell cannot schedule the second cell or that the first cell cannot schedule any cell;

(2) Before transmitting fourth control information (the fourth control information indicates that the first cell or first cell group is non-dormant)

Here, the first control information, the second control information, the third control information, and the fourth control information are control information indicated by DCI or MAC CE on the first cell and/or second cell, or control configured through RRC signaling. It may be information, and is not specifically limited in the present application.

(3) before the first cell is activated

(4) before the first cell is reconstructed

(5) Before the third timer of the first cell is started

Here, the third timer may be a cell inactive timer. Optionally, after the third timer runs, the first cell deactivation countdown is entered, and after the third timer times out, the first cell is deactivated.

(6) Before the second target BWP of the first cell is activated (the second target BWP is a BWP capable of scheduling the second cell)

(7) Before the second target BWP of the first cell is reconstructed

(8) Before the fourth timer of the second target BWP of the first cell is started

Here, the fourth timer may be a BWP inactive timer of the second target BWP. Optionally, after the fourth timer runs, a second target BWP deactivation countdown of the first cell is entered, and after the fourth timer times out, the second target BWP of the first cell is deactivated.

Through the above possible implementation, after the first cell is switched to an inactive or non-dormant state, or the first cell is switched to a BWP capable of scheduling the second cell, the target blind detection budget of the terminal is determined again, Adjustments to the target blind detection budget can be implemented.

In one possible implementation, the target mapping method determined in (B) below may also be applied to the time, but may not be applied only to the time, and is not specifically limited in this embodiment.

(B) Determination of target mapping method

In an embodiment of the present application, after the terminal is configured or switched to the second scheduling configuration or the third scheduling configuration, if at least one of the first conditions is satisfied, the mapping scheme of the terminal may be adjusted. .

In one possible implementation manner, if scheduling of the second cell by the first cell is regarded as a blind detection budget of the second cell, in S210, a target mapping method is determined according to the scheduling configuration of the first cell and/or the second cell. Determining is that if the scheduling configuration is a second target configuration or a third target configuration and also satisfies the first condition, when performing mapping of the control unit of the second cell in one scheduling time unit, the second It may include mapping a control unit that the second cell itself schedules onto a physical control resource of the cell.

In other words, when mapping the control unit of the second cell in one scheduling time unit, the control unit that the second cell itself schedules is mapped onto the physical control resource of the second cell.

For example, the search space for scheduling the second cell itself is SS#0/1/2/3/5/6, and the search space for the first cell to schedule the second cell is SS#4. If the first cell or the Scell group in which the first cell is located in the second cell or the first cell is dormant, the first cell is inactive, or the BWP of the first cell (which can schedule the second cell) When switching occurs, or when indicating that BWP inactivation of the first cell (capable of scheduling the second cell) is indicated, when mapping the search space on the physical control resource of the second cell, according to the mapping order, first SS#0/1/2/3 are mapped, then SS#5/6 are mapped.

In the above possible implementation manner, within one scheduling time unit, the total number of mapped control units does not exceed the maximum blind detection number of control units of the second cell. That is, the total number of control units mapped onto the physical control resources of the second cell does not exceed the maximum blind detection number of the control units of the second cell. In other words, mapping to the nearest search space without exceeding the maximum blind detection number P of the control unit of the second cell, and if there is a search space that has not yet been mapped, mapping is not continued.

Here, the maximum number of blind detections of the control unit of the second cell may be the maximum number of blind detections of the control unit of the second cell in the target blind detection budget determined by each implementation method in (A) above, or by using another method. It may be determined, and is not specifically limited in the present application.

In another possible implementation, the blind detection of the control unit in which the first cell schedules the second cell (i.e. the first cell schedules the SS of the second cell) may be assigned to the blind detection share of the first cell, That is, scheduling of the second cell by the first cell belongs to the blind detection budget of the first cell.

In the above possible implementation manner, in S210, determining the target mapping method according to the scheduling configuration of the first cell and/or the second cell, if the scheduling configuration is the second scheduling configuration or the third scheduling configuration, and also the If condition 1 is satisfied, when mapping the control unit of the first cell in one scheduling time unit, the control unit that the first cell self-schedule is mapped on the physical control resource of the first cell, and/ Alternatively, it may include mapping a control unit for scheduling a third cell by the first cell onto a physical control resource of the first cell. In a possible implementation, when mapping the control unit of the first cell within one scheduling time unit, the control unit that the first cell itself schedules is mapped.

For example, the search space in which the first cell itself schedules is SS#4/6, the search space in which the first cell schedules the second cell is SS#5, and any one of the first conditions is satisfied. If so, when the search space is mapped on the physical control resource of the first cell, SS#4 is first mapped, and then SS#6 is mapped according to the mapping order.

In the above possible implementation manner, optionally, within one scheduling time unit, the total number of mapped control units does not exceed the maximum blind detection number of control units in the first cell. For example, the total number of control units mapped on the physical control resources of the first cell does not exceed the maximum blind detection number of control units of the first cell.

Optionally, in the above possible implementation manner, a self-scheduled control unit of the first cell may be mapped onto a physical control resource of the first cell. Optionally, the number of mapping control units that the first cell self-schedules cannot exceed the maximum blind detection number of control units of the first cell.

Optionally, in the above possible implementation manner, a control unit for self-scheduling of the first cell is mapped onto a physical control resource of the first cell, and/or a physical control unit of the first cell is mapped onto a physical control resource of the first cell. A control unit that schedules this third cell is mapped. Here, one mapping sequence is to first map the control units that the first cell itself schedules, and if the number of mapping control units that the first cell itself schedules is the maximum blind detection number of the control units of the first cell. If not exceeded, the first cell may map a control unit for scheduling the third cell onto the physical control resource of the first cell.

In other words, mapping to the nearest search space without exceeding the maximum blind detection number S of the control unit of the first cell, and if there is a search space that has not yet been mapped, mapping is not continued.

In another possible implementation, the blind detection of the control unit for scheduling the second cell by the first cell may also be allocated to the joint share of the blind detection of the first cell and the second cell, and the first cell schedules the second cell. The scheduling blind detection budget belongs to the first cell and the combined blind detection budget of the first cell.

Therefore, in a possible implementation manner, determining the target mapping method according to the scheduling configuration of the first cell and/or the second cell in S210, if the scheduling configuration is the second scheduling configuration or the third scheduling configuration, and If the first condition is satisfied, when the control unit of the first cell and/or the second cell is mapped in one scheduling time unit, the second cell performs self-scheduling on the physical control resource of the second cell. It may include mapping a control unit, and/or mapping a control unit that the first cell itself schedules onto a physical control resource of the first cell. In other words, in the possible implementation, when mapping the first cell and/or the control unit of the first cell within a scheduling time, the second cell self-scheduling and/or the first cell self-scheduling Map the control unit to

In the above possible implementation manner, optionally, within one scheduling time unit, the total number does not exceed an associated maximum blind detection number of control units of the first cell and the second cell.

It should be explained that, in the technical solution according to an embodiment of the present application, when mapping a control unit to a first cell, the control unit that the first cell self-schedules and the first cell controls the scheduling of the second cell. In addition to the unit, there may also be a control unit for the first cell to schedule other cells. In the present application, the mapping of the control unit that the first cell schedules other cells is not described, because in the present application, the control unit and the first cell that the first cell itself schedules are mainly in the first cell. It has been described whether a control unit that schedules the second cell needs to be mapped, and whether or not the first cell has a control unit that schedules other cells is not limited in the present application.

g) the maximum blind detection number S-selfandother of control units (including but not limited to PDCCH, CCE or SS) for which Scell#1 schedules itself and other Scells;

h) at least one of the combined maximum blind detection number T of the Pcell and the control unit (including but not limited to PDCCH, CCE or SS) of Scell#1, but is not limited thereto.

Taking the number of blind detections of the control unit in the SP-CR-SS or the control unit for which Scell#1 schedules Pcell in the SP-CR-SS as the budget of Scell#1 or Pcell,

b) Among the SP-CR-SS, blind detection of the control unit in which Scell#1 schedules Pcell is allocated to the blind detection share of the scheduling cell (ie, Scell#1), and CR can be regarded as a part of S if there is;

c) Among the SP-CR-SS, Scell#1 assigns blind detection of the control unit scheduling Pcell to the combined blind detection share of Pcell and Scheduling cell (ie, Scell#1), and CR can be considered as part of T. case can be distinguished.

Optionally, the methods a), b), or c) may be used through protocol regulation, network-side device configuration, or terminal selection, and the embodiments of the present application are not specifically limited.

In an embodiment of the present application, there are three scheduling configurations, the first scheduling configuration, the second scheduling configuration, and the third scheduling configuration, specifically, when the first cell is Scell#1 and the second cell is Pcell, These three scheduling configurations are respectively as follows.

4) The Pcell's BWP (which can schedule the Pcell) is deactivated. For example, the Pcell's BWP does not configure the BWP inactive timer or the inactive timer has expired.

In one possible implementation, if Scell#1 determines that scheduling the Pcell belongs to the blind detection budget using the above method a), when at least one of the cases described in 1) to 4) appears, one following Within/after the period, or before receiving control information that the Pcell or the cell group in which the Pcell resides is non-dormant, or the Pcell is activated/reconfigured/timer started, or the Pcell's BWP (which can schedule the Pcell) is activated /reconfiguration/timer Before starting, the terminal's blind detection budget may include at least one of the following.

The base station configures a new P' and/or S'; and/or the base station configures a new S-self' and/or CR'; and/or S-selfandother', that is, the base station configures a set of blind detection budget parameters corresponding to the first scheduling configuration for the terminal, where P', S', S-self', CR' and S-selfandother'.

In one possible implementation, P', S', S-self', CR' and S-selfandother' are P'=0; S'>=S; S-self'>= S-self; CR'>CR; At least one of S-selfandother'>= S-selfandother may be satisfied.

In one possible implementation manner, if Scell#1 determines that scheduling the Pcell belongs to the blind detection budget using the above manner c), when at least one of the cases described in 1) to 4) appears, one following Within/after the period, or before receiving control information that the Pcell or the cell group in which the Pcell resides is non-dormant, or the Pcell is activated/reconfigured/timer started, or the Pcell's BWP (which can schedule the Pcell) is activated /reconfiguration/timer Before starting, the terminal's blind detection budget may include at least one of the following.

(B) When the first cell is Scell#1, the second cell is Pcell, and the scheduling configuration is the first scheduling configuration, the mapping method may be determined through the following method.

In one possible implementation, if, using scheme a) above, it is determined that Scell#1 scheduling a Pcell belongs to the blind detection budget, i.e., if Scell#1 scheduling a Pcell belongs to the Pcell budget, 1) When at least one of the cases described in ~ 4) appears, the mapping method may be determined according to the following method.

When control information mapping for scheduling the Pcell in one scheduling time unit (eg, occasion/span/slot) is performed, control information other than scheduling by the Pcell itself is mapped. For example, the search space in which Pcell schedules itself is SS#0/1/2/3/5, the search space in which Scell#1 schedules Pcell is SS#4, and the search space in which Pcell schedules Scell#2 is SS#2. The search space is SS#5/6, and if the terminal is a Pcell or Scell#1 is a Pcell or a cell group in which the Pcell is located is dormant, Pcell is inactive, or a transition occurs in the Pcell's BWP (Pcell can be scheduled) or when receiving control information indicating that the Pcell's BWP (capable of scheduling the Pcell) is inactive, the UE first maps SS#4 onto the physical control resource of Scell#1, and then maps the physical control resource of the Pcell SS#5/6 is mapped on the control resource.

Optionally, in the above mapping scheme, the mapped control unit does not exceed P and up to the nearest control unit, and if there is a control unit that has not yet been mapped, no further mapping is performed. Here, the maximum blind detection number P of Pcell may be the maximum blind detection number according to Pcell in the blind detection budget according to the embodiment of the present application.

In one possible implementation, if, using scheme b) above, it is determined that Scell#1 scheduling the Pcell belongs to the blind detection budget, i.e., if Scell#1 scheduling the Pcell belongs to the Scell#1 budget, When at least one of the cases described in 1) to 4) appears, the mapping method may be determined according to the following method.

When mapping a control unit that schedules a Pcell in one scheduling time unit (occasion/span/slot), a search space excluding the Pcell scheduling itself is mapped. For example, the search space in which Scell#1 itself schedules is SS#6, the search space in which Scell#1 schedules Pcell is SS#5, and if Pcell or Scell#1 is Pcell or the cell where Pcell is located, When the group receives control information indicating that the dormant, or Pcell inactivation, or a transition to the Pcell's BWP (capable of scheduling the Pcell) has occurred, or the Pcell's BWP (capable of scheduling the Pcell) inactivation, When mapping the search space on the physical control resource of Scell#1, the UE first maps SS#5 and then maps SS#6.

Optionally, within one scheduling time unit, it does not exceed S and maps to the nearest search space, and if there is a search space that has not been mapped yet, no further mapping is performed.

In one possible implementation, if, using scheme c) above, it is determined that Scell#1 scheduling the Pcell belongs to the blind detection budget, i.e., if Scell#1 scheduling the Pcell belongs to the joint budget, then 1) When at least one of the cases described in ~ 4) appears, the mapping method may be determined according to the following method.

When performing control unit mapping that schedules Pcells and/or control units of Pcells in one occasion/span/slot, Scell#1 schedules itself and/or Scell#1 maps control units that schedule Pcells.

(C) When the first cell is Scell#1, the second cell is Pcell, and the scheduling configuration is the second scheduling configuration or the third target device configuration, the blind detection budget may be determined through the following method.

After being configured or switched to the second scheduling configuration or the third target device configuration, when at least one of the following cases occurs, Scell#1 is unable to schedule a Pcell (but can schedule itself and/or other Scells) , or Scell#1 may not be able to schedule any cell.

(a) Scell#1 or Scell group where Scell#1 is located is indicated as dormant by DCI;

(b) Scell#1 is inactive, for example, the inactive timer of Scell#1 is not configured, or the inactive timer of Scell#1 expires, or is indicated to be inactive by MAC CE, RRC or DCI;

(c) the BWP of Scell#1 (capable of scheduling Pcell) is switched, for example, switched to BWP not capable of scheduling Pcell;

(d) BWP (capable of scheduling Pcell) of Scell#1 is deactivated, for example, the BWP inactive timer is not configured or the inactive timer expires.

In one possible implementation, if, using scheme a) above, it is determined that Scell#1 scheduling the Pcell belongs to the blind detection budget, that is, if Scell#1 scheduling the Pcell belongs to the Pcell budget, (a) ) to when at least one of the cases described in (d) appears, within/after one succeeding period, or before Scell#1 or the Sell group in which Scell#1 is located receives DCI of ql dormant, or Scell#1 Before this activation/reconfiguration/timer is activated or the BWP (which can schedule Pcell) of Scell#1 is activated/reconfigured/timer activated, the UE's blind detection budget may include at least one of the following.

1. CR=0 and/or P-self=P;

2. The base station configures a new P-self' and/or P', that is, the base station configures a set of blind detection budget parameters corresponding to the second scheduling configuration or the third scheduling configuration for the UE, where P -self' and/or P'.

Optionally, P-self'> = P-self, and/or P'>= P, where P-self and P are values of another set of blind detection budget parameters configured by the base station for the UE.

When any one of (a) to (d) above occurs, since Scell#1 cannot schedule Pcell, Pcell can proceed with self-scheduling only through Pcell's own control information. Adjustments can be made to the number of blind detections, for example, the maximum number of blind detections of Pcells, i.e., allowing more Pcells to schedule themselves, to fully utilize the number of blind detections in idle state.

Optionally, Pcell itself schedules or P-self includes CSS#3, that is, group common PDCCH.

In one possible implementation, if, using scheme b) above, it is determined that Scell#1 scheduling Pcell belongs to the blind detection budget, i.e., if Scell#1 scheduling Pcell belongs to Scell#1 budget, (a) When at least one of the cases described in (d) occurs, within/after one succeeding period, or before Scell#1 or the Sell group in which Scell#1 is located receives a DCI of ql dormant, or Scell Before #1 is activated/reconfigured/timer activated or BWP (which can schedule Pcell) of Scell#1 is activated/reconfigured/timer activated, the UE's blind detection budget is calculated according to the following method 1, method 2 or method 3 Any one of these may be included.

Here, method 1 may include any one of the following.

(a) CR=0 and/or S-self=S. Optionally, Scell#1 is dormant, or Scell#1 is inactive, or Scell#1's BWP (which can schedule Pcell) transitions, or Scell#1's BWP (which can schedule Pcell) When Scell#1 indicates that Pcell is inactive, this method can be used to indicate that Pcell cannot schedule.

(b) The base station configures a new S-self', that is, the base station configures a set of blind detection budget parameters corresponding to the second scheduling configuration or the third target scheduling for the terminal, and S-self' is configured here. include

Optionally, S-self' >= S-self.

Optionally, Scell#1 is dormant, or Scell#1 is inactive, or Scell#1's BWP (which can schedule Pcell) transitions, or Scell#1's BWP (which can schedule Pcell) If Scell#1 indicates that Pcell is inactive, Method 1 may be used to indicate that Pcell is not capable of scheduling.

Since Scell#1 cannot schedule Pcell at this time, Scell#1 can only schedule cells other than Pcell (for example, Scell#1 itself), thus adjusting for maximum blind detection number of S-self in method 1 , for example, is the maximum number of blind detections of Scell#1, that is, allows more Scell#1 to schedule itself, making full use of the number of blind detections in the idle state.

Here, method 2 may include any one of the following.

(a) CR=0 and/or S-selfandother=S;

(b) The base station configures a new S-selfandother', that is, the base station configures a set of blind detection budget parameters corresponding to the second scheduling configuration or the third target scheduling for the terminal, and S-selfandother' is configured here. include Optionally, S-selfandother'>=S-selfandother.

Optionally, Scell#2 is dormant, or Scell#1 is inactive, or Scell#1's BWP (which can schedule Pcell) transitions, or Scell#1's BWP (which can schedule Pcell) If Scell#1 indicates that Pcell is inactive, Method 1 may be used to indicate that Pcell is not capable of scheduling.

Since Scell#1 cannot schedule Pcell at this time, Scell#1 can only schedule cells other than Pcell (e.g. Scell#1 itself and/or other Scells), so when CA limited, Scell#1 Since a change occurs in the number of cells to be scheduled, in method 2, adjustment can be made for S-self and other, for example, to the maximum blind detection number of Scell#1, that is, more Scell#1 can schedule itself. At this time, the number of blind detections in the idle state is sufficiently used.

Here, method 3 may include adjusting S=0, that is, the maximum blind detection number S of the control unit of Scell#1 to 0.

Optionally, Scell#1 is dormant, or Scell#1 is inactive, or Scell#1's BWP (which can schedule Pcell) transitions, or Scell#1's BWP (which can schedule Pcell) indicates inactive, it means that method 3 is used when Scell#1 cannot schedule any cell.

In one possible implementation, if, using scheme b) above, it is determined that Scell#1 scheduling Pcell belongs to the blind detection budget, i.e., if Scell#1 scheduling Pcell belongs to the joint budget, (a ) to when at least one of the cases described in (d) appears, within/after one succeeding period, or before Scell#1 or the Sell group in which Scell#1 is located receives DCI of ql dormant, or Scell#1 Before this activation/reconfiguration/timer is activated or the BWP of Scell#1 (which can schedule Pcells) is activated/reconfigured/timer activated, the UE's blind detection budget is determined by Scell#1 scheduling a control unit other than the Pcell. The maximum number of blind detections = the combined maximum number of blind detections T of the Pcell and the control unit of Scell#1.

(D) When the first cell is Scell#1, the second cell is Pcell, and the scheduling configuration is the second scheduling configuration or the third scheduling configuration, the mapping method may be determined through the following method.

In one possible implementation, if, using scheme a) above, it is determined that Scell#1 scheduling the Pcell belongs to the blind detection budget, that is, if Scell#1 scheduling the Pcell belongs to the Pcell budget, (a) ) to (d), when at least one of the cases described in (d) appears, the mapping method may be determined according to the following method.

When performing control information mapping for scheduling a Pcell in one scheduling time unit (eg, occasion/span/slot), a search space in which the Pcell schedules itself is mapped. For example, the search space in which Pcell schedules itself is SS#0/1/2/3/5/6, the search space in which Scell#1 schedules Pcell is SS#4, and if Pcell or Scell#1 This Scell#1 or the Scell group in which Scell#1 resides is dormant, or Scell#1 is inactive, or Scell#1's BWP (Pcell can be scheduled) transitions, or Scell#1's BWP (Pcell can be scheduled) When receiving control information indicating inactivation, the UE first maps SS#0/1/2/3 and then SS#0/1/2/3 when mapping the search space on the physical control resource of the Pcell. Map #5/6.

Optionally, map up to the closest control unit without exceeding the maximum blind detection number of the control unit of the Pcell, and if there is a control unit that has not yet been mapped, no further mapping is performed.

In one possible implementation, if, using scheme b) above, it is determined that Scell#1 scheduling the Pcell belongs to the blind detection budget, i.e., if Scell#1 scheduling the Pcell belongs to the Scell#1 budget, When at least one of the cases described in (a) to (d) appears, the mapping method may be determined according to the following method.

When mapping a control unit that schedules Scell#1 in one scheduling time unit (occasion/span/slot), Scell#1 maps a control unit that schedules itself. For example, the search space in which Scell#1 schedules itself is SS#4/6, the search space in which Scell#1 schedules Pcell is SS#5, and if Pcell or Scell#1 is Scell#1 or Scell The Scell group in which #1 resides is dormant, or Scell#1 is inactive, or Scell#1's BWP (capable of scheduling Pcells) has a transition, or Scell#1's BWP (capable of scheduling Pcells) Upon receiving the control information indicating that it is inactive, when mapping the search space on the physical control resource of Scell#1, the UE first maps SS#4 and then maps SS#6.

Optionally, map up to the closest control unit without exceeding S, and if there is a control unit that has not yet been mapped, do not continue mapping.

In one possible implementation, if, using scheme b) above, it is determined that Scell#1 scheduling Pcell belongs to the blind detection budget, i.e., if Scell#1 scheduling Pcell belongs to the joint budget, (a ) to (d), when at least one of the cases described in (d) appears, the mapping method may be determined according to the following method.

When performing mapping of the control unit that schedules Scell#1 and/or Pcell in one scheduling time unit (occasion/span/slot), the control unit that Pcell schedules itself and/or Scell#1 schedules itself map
